citizen of the .l nitcd States. i'e. irliu-;1' of: liridr'cport. in thccouuty of Fnirlicld'nnd Stale oi" ionnccticut. have invenl -d certain now and useful lin n'ovenu nts in Rough iiound rs or .linnnclcrsi oi which the following is a specification, rota-renew being had therein to tho u'compzinying drawings.

In r igzh rounding and channeling nuichincs as usually wnstrueted. the cluinncling lcni l'c held in :1. slot in the upper surface of n kuii'c holder its *ihrwnrd and bring bent suiistnntinlly pnrnllcl to tho forward face of the holder whet-c it is provided with a lateral. cuttin mlgc, {ho forward face of the holdcr lurnrdiim; :r snr'l'iu-o against which the worla is hcld during: tho channelinoo 'crn" ,n. is if c knife HSfix'l and rcslmrpcncd ii. has. bccn iound thin; considerable snarl-1. may h s loft hctwven tho cutting cd c oi the knife and the iorli{imaging surlzu'c oi the holder which til furnishes no support for thewori rloscly :ulj-zuwent the cutting cdggc, in'ipairiug qunity of the work of the machine.

To avoid this objcction this ini'cntion prim rides an .ialjistuhlc .rorlii-cngiuringlj l'zu'o for the: knife holder which may he. moved hitcrall thcreoi' toward tho cutting edge of the knife ii. nrdcr to insurc support for the work closely adjacent thcrctof Another difiiculty a'xg'icricnced with these machincs as usually consiructcd in the; fact that as the. Cllttliljjf ethic of the channel knife is ground away its operutin n position with rchition to the other pnr's of tho Inuchinc This matter of more im- Jortnncc where the above-mentioned adjust able worlocngaging fLIt'C is cmpioycd, as the knife may then. us ground considerably further back than heretofore without otherwise interfering with the operation of thmmachins In order, therefore, to take more complete advantage of the construction above-mentioned, this invention further provides mom whereby the. cdgc of the knife may be adjusted relative to other parts of the nurchinc so that repeated grinding may not cause it to be incorrectly related thereto.

More specifically it provides means for no.

I in. 5 is a section taken on the line 5-5 partly in section, the section being taken on hcrSPcctivc'viw of tho chanfrhat it is free to oscillate about a center substantially at the Forward iippcuend thereof." Block 3 IS coin posed of two members 4t and 5 member 5 harm a. "Rule )nn 6 thereonpartly in scction of an showing adapted to engage ina perforation 7 of membar 4-. A bolt 8 passes through [a perforation in the member 4 and engages g1 screw threaded opening 9 in tho mcmber 5, the head 10 of this bolt being carricn in a recess 11 in the outer face of member at. Member i has along its upper surfaces recess 12 and opposite thereto the member 5 has dove-tail recess 13.."lhc shank "14 of a channeling knife 15 may be. positioned withinfiic recesses 12 and 13 and on tighten ing theholt- 10 may be made fastthereiu by means of tbs dovetail formation of tho recess 5 engaging the corresponding portion of thc'shank 14. As shown, the shonk l4 en tends rearwardly from the block 3 and through a slot in the -portion 2', the bottom of which at 16 maybe engaged by the knife shank to prevent the separation. of block 3 from the bar 1 in a downward direction. The forward end ofthe knife'lfi is turned downwardly at 17 into substantially parallel relationto the forward face of the block 3 and is provided at its lateral face with a cutting edge 18 The member 4 has in its forward face a lateral groove 1.9 for the reception of a mating tongueBO carried on the rear faceof a work-engaging plate 21. A; screw the head of which is seated in a sulistantially fiatrecess 23 in the forward face of the plate 21,passing through a slot 24: therein and threaded into the portion 4:, serves to retain the plate 21 in position with capability of lateral adjustment across the 'liOlWVRI'l'l face of the member,- 4 toward and from the cutting edge 18 of the knife. When the knife ,is new it is formed substantially as shown in solid line in Fig. 6, but after use and resharpening the'knife blade becomes narrowrelation to other operative mechanisms of the machine regardless of the amount to which the edge of the knife may have been ground back, the mechanism illustrated in F 4, 7 and8 has been provided these figures showing the invention applied to a rough rounding machine of the type disclosed in the patent to Valois, 1,118,883, Nov. 24, 1914:,to which reference may be had for details of construction, not herein shown.

In these figures, 30 represents the main drive shaft of the machine carrying an eccentric 31. Journaled on this eccentric is the rear end'of a link 32 pivoted at 33 to the rear end ,ofa chopping knife bar 34, this bar carrying at its forward end the chopping knife for rough rounding the sole of shoe :1 ft'er attachment to the welt. l rcjecting from the lower face of the bar 34-. is a pin engaging:- within an angular slot 36 in a plate 37, this plate forming a cover for a guiding block 38 to which it is attached by screws 39. lllockBR has a channel d, upper face in which channel the channeling knife bar 1 is slida bl'y mounted, a guide pin 4:0 extel'iding; tl'irough a. slot 41 of the bar 1 and seated in the sidcsot' the block 37 serving to retain the bar '1 in position. Mount ed in the frame A of the machine is astud 42 formed above the frame A as an eccentric 43, surmounted by a concentric knob 44. provided with a transverse opening 45, With in the frame A the stud 42 has a periohera'l groove 46 therein, and a set screw 47 seated within the frame A within this groove 46 to retain the stud 4C2 in position and to prevent it from rotating when set screw 4:7 is tightened thereagainst. Journaled on the eccentric portion 4W is the rear end of a lever 48, the forward end which is made fast to or is integral with the block 37. If desired an indicating plate so may I be attacl'led to the stud 42 immediately above the lever 4-8, this plate carrying a pointer 50 cooperating with suitable indices marked on the lever as, by which means the position of the eccentric may be easily determined. Depending from the link 32 is whose 51. Bearing between this boss and a socket 52 in the rear end of channel knife bar 1 is a coil. spring 53 which normally urges the bar '1. to its forward limit of motion as determined by the pin 40 and slot 41. Extending laterally from. the bar 1 is a pin 54 which maybe engaged by one end of a lever 55 connected to any suitable treadle mechanism (not shown) by which the bar 1 carrying the channeling knife may be retracted against the pressure of the spring by the operator at will, as disclosed in the above-mentioned patent.

The operation of this mechanism is follows. Rotation of the shaft 30 acting through the eccentric 31 serves to reciprocate the link 32 and the chopping knife bar as which imparts the ciltting stroke to the edge trimming knife. Movement of the pin 35 within. the slot 36 causes a lateral movement of the channel knife bar 1 due to the angular position of the slot '36 with relation to the plate 37. this motion giving the operative movements to the channel knife block and hence to the channel knife 15. The spring 53 holds the channel knife block outwardly against the work, the force of the spring being" increased on the outward stroke of the bar 34 and the working: stroke of the channel knife, by the motion of the lug 51 toward the rear end of the bar 1. this action being substantially as shown and described in the patent tb Valois, above noted.

As the channel knife 15 is ground away the cutting edge thereof travels relative thereto toward the left shown in F igs. 2 and 4-. In order to adjust it into proper relative position to the chopping knife it is only necessary to release the set screw 4-? slightly, insert a suitable ,tool in. the opening 45 in knob 44 and turn the stud 42, the eccentricity of the portion 43 moving the fulcrum of the lever 43 turning' the lever 4-8 about the pin 35 a center and swinging the forward end of the bar '1 and with it the cutting edge of the, knife. By suitably positioning the eccentric 43, it is thu-sseen that the bar 1- and block it may be adjusted to suit the position of the cutting edge of the channel knife to adjust the initial and final positions of its path of motion in proper relation to the other parts of the machine, By this nieai it-iuay be seen that the knife blade can fie sharpened till its width is materially decreased without quality of its work.

While this invention has been shown as applied to a channelingknife holder; it will be evident. to those skilled in-the art that it may also find application in other situations where it is desired to support work closely adjacent-the working portion of a tool, the position of which may vary from time to time.
